February 2025 in “JEADV Clinical Practice” This study described a rare case of bullous pemphigoid presenting as cicatricial alopecia in a Hispanic female, successfully treated with a combination of oral methotrexate and topical steroids.
November 2024 in “Journal of Drugs in Dermatology” This review found that platelet-rich plasma may have a positive effect on scarring alopecia by slowing progression and reducing inflammation, though evidence remains limited to case reports.
February 2024 in “Journal of Cellular and Molecular Medicine” In this study using rat models, researchers developed a Pluronic@F-127 hydrogel to deliver the flavonoid pectolinarin, finding it accelerates wound healing and reduces scar formation by enhancing cell migration, proliferation, and antioxidant activity.
November 2023 in “Journal of Investigative Dermatology” This research investigated immune cell involvement in various types of inflammatory alopecia by analyzing gene expression data from scalp samples, revealing distinct cellular changes in conditions like Alopecia Areata, Frontal Fibrosing Alopecia, Lichen Planopilaris, and Central Centrifugal Cicatricial Alopecia, which may inform future therapeutic targets.
October 2023 in “bioRxiv (Cold Spring Harbor Laboratory)” This study demonstrated that disrupting EGFR signaling in mice leads to immune sensitivity compromising the hair follicle's protective environment, but JAK1/2 inhibition can restore this immune privilege and stimulate hair growth, suggesting a potential therapy for scarring hair loss diseases like cicatricial alopecia.
June 2023 in “Clinical Case Reports” This report describes a woman with microcystic adnexal carcinoma who underwent successful excisional surgery and hair transplantation, which may be beneficial for treating surgical scars.
April 2023 in “Authorea (Authorea)” Hair transplantation can improve scars after removing a rare skin cancer.
August 2018 in “Analysis of the application of various variants of bone plasty in victims with intraarticular fractures (Transplantology)” In this study, follicular microautotransplantation was found to be an effective outpatient surgical treatment for scarring alopecia, with transplanted follicles showing an average engraftment rate of 93.8% and providing a good cosmetic outcome that improves patients' quality of life.
December 2012 in “Drugs & Therapy Perspectives” Doctors use their experience to choose treatments for scarring hair loss because it's hard to diagnose and treat.
July 2026 in “Frontiers in Immunology” This review explores the mechanisms of wound-induced hair follicle neogenesis in mice, discussing its potential to inform precision therapies for alopecia and scarless wound healing, but reports no new clinical results.
